Abstract
The standard metabolic rates of similarly sized juvenile diploid and triploid brook charr were estimated by using intermittent-flow respirometry to measure oxygen uptake over a 10-day fasting period. Initial oxygen uptake rates did not differ between ploidies, but the rate of decline was slower in triploids, resulting in higher final oxygen uptake rates and, therefore, higher estimated standard metabolic rates. Based on other studies that have shown no effect of triploidy on maximum metabolic rate, this implies reduced aerobic scope in triploids.
